Method for manufacturing bags with gussets

摘要

The method involves conducting a sheet (11) through a folding station (13), where side gussets are formed by folding of the sheet. A foil slip (9) has edge sections (14) that are fused with an underlying seal section of the sheet. The sheet is folded toward a foil tube (15), where the tube processes toward a foil pouch. Application and fixation of the foil slip and a sealing operation of side gussets are assigned to different working stations.
